The public pool is checked before anything is shown.
Use the instrument. Read its boundary.
Each door is labelled by its real operating state. Live tools wait for source-backed responses; decision-only tools explain their rules; preview doors cannot imitate a completed result.
Network failure, empty coverage, contract mismatch, withdrawal, and rate limits render explicit states. No fixture or remembered result replaces them.
Start with the problem in front of you.
Tools are grouped by the action they can complete now, not by a large product taxonomy.
Sample question
Answer one reviewed JEE or NEET question and receive the result only after server-side submission.
- No score prediction
- No private practice history on the website
College predictor
Put an existing rank against the public cutoff projection and inspect the source and limitations.

Cutoff explorer
Search the canonical college index, select a college, and inspect available cutoff rows.

- Official counselling rules remain authoritative
Chapter map
Browse the exam-scoped concept graph by subject and chapter without an unscoped fallback.

- Empty source states remain empty
Preparation route finder
Choose the problem in front of you and receive a next public action—not an invented paid-plan recommendation.
- No price or entitlement advice
- Not a personalised study plan
Grading boundary
Inspect what a public grading workflow would require before submitting work in the app.
- No fake grade
- No live public grading API yet
Three checks before any public outcome.
Validate the request
Unsupported exams, percentile conversion, incomplete searches, and malformed answers stop before result rendering.
Validate the source
The API envelope must carry source identity, state, freshness, methodology, coverage, and a request ID.
Carry only useful context
App entry can carry the touched public object through continuity. Exact restoration remains separately gated until app proof exists.
